Abstract

L'invention concerne un instrument de mesure d'impédance qui peut être utilisé pour mesurer avec une précision élevée la quantité de fines particules déposées sur un moyen de collecte de fines particules. L'instrument de mesure d'impédance d'un collecteur de fines particules (1) comprend un corps de collecte de fines particules (2) pour collecter de fines particules dans un fluide, un corps de boîte conducteur (3) pour contenir le corps de collecte de fines particules (2), et un corps d'amortissement (4) disposé entre le corps de collecte de fines particules (2) et le corps de boîte conducteur (3). Selon l'invention, deux électrodes (7), ou plus, sont disposées sur le corps de collecte de fines particules (2), au moins l'une des électrodes (7) étant reliée à une source d'alimentation en courant alternatif (8), au moins l'une des autres électrodes (7) étant reliée à un ampèremètre (9), la source d'alimentation en courant alternatif (8) et l'ampèremètre (9) étant interconnectés et reliés en outre avec le corps de boîte conducteur (3), et le corps de boîte conducteur (3) étant mis à la masse.
